| Abstract: | Sometimes frequency converter failures occur in a top lance for refining of liquid steel in domestic metallurgic industry, so that the top lance can not quickly and auto- matically lift out of a vacuum tank and the top lance can be burned easily. A new control circuit for a lifting device of the top lance has been developed and it can improve safety and reliability of the top lance device. |
